Just installed new battery in 89 jeep comanche but still wont start. it has lights, radio. etc. and it jump starts.

IT costs nothing to have a load test done on the battery to check for a dead cell which your problems point to. While the engine is running the alternator will be handling the power requirement but the battery will not supply the power required to start.

You got a jump and it ran fine? It's your battery. The lights and radio are much easier for a battery to handle than spinning a car engine. Again, if all you needed was a jump, you have a bad battery.

Sounds like a body ground, I would start there.

Alternator isnt charging. go to a parts store and have it tested

If is fuel injected try checking the fuel regulator and if is has a carburetor possible bad choke or needle seat / worse case jump timing

if you have theft security problems if you jump start the vechicle it still wont crank.have battery load tested and checked battery could be weak.your current drain can be caused by many things, like radio,faulty power lock, dome light remain on,faulty pcm,faulty alternator,faulty heater blower motor relay.

Replace the ignition switch, which is behind the lock cylinder.

I take it that it cranks over but will not start. Spray some starter fluid into the throttle body. If it runs, you have a fuel problem. You may have disconnected the fuel system by unplugging a connector or grounding a wire blowing a fuse.

sticky choke maybe, try carb cleaner, check the air-cleaner filter,depending on were you live, maybe some dry gas.from the symtom's sounds like it's chocking out,those are the easy cheap thing's first, now check the fuel filter, then the fue pump, prividing your getting good spark to fire up the fuel,good luck

Replace the crankshaft position sensor
